Hey Imperialists! My brakes have been feeling a bit spongy of late, and they seem to be getting less effective. They work but they dont work with as much ease as they used to. In fact, the other day, I could hear one of them dragging: I came to a stop, pulled my foot off of the brake and heard that metal screeching sound as the car lurched forward. This has only happened once, but it concerned me enough to check the master cylinder. Sure enough, I was low on Brake oil. The brake oil that was in there was also quite dark. Anyway, I next checked for leaks, on the inside of the tires,and I havent been able to find anything yet. There are no leaks coming from the master cylinder itself. Is it possible that the leaks are going into the vacuum booster unit? I hear a hissing sound when I put full pressure on the brake pedal, which usually indicates a leak in the vaccuum booster. Maybe this is what is giving me less than standard brake performance. I am no mechanic and this is the first car i have ever owned, so any helpful opinions would be great! Also, my Imperial sat in a garage for 16 years without being started once. I got the car going last year with my uncle, and we checked the original brakes, everything seemed to be in good condition, except the master cylinder, which we replaced. Could the brake cylinders have corroded just sitting there? Thanks again, Raffi in SF 62 Crown Coupe, 62K original miles
